Description

Technical Field

[0001] This utility model relates to the field of large-scale testing equipment and long-stroke loading equipment, and in particular to an automatic clamping support and stroke beam traveling device. Background Technology

[0002] Many machines require space adjustment, and after adjustment, the adjustment parts are fixed and locked in order to work. Generally, hydraulic cylinders are used to push them. However, when the space to be adjusted is very large, due to the limitations of the hydraulic cylinder manufacturing process, it is impossible to make hydraulic cylinders with particularly long strokes. Cylinders with strokes of more than ten meters or tens of meters cannot be made or the manufacturing cost is too high.

[0003] Existing technologies use long-stroke lead screws in conjunction with electric or hydraulic motors to solve the problem of long-stroke beam travel. However, long-stroke lead screws require high machining accuracy and have certain limitations in their stroke. Furthermore, the machining cost of long-stroke lead screws is relatively high, increasing the operating cost. Therefore, an automatic clamping support and travel beam travel device is proposed to solve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an automatic clamping support and travel beam traveling device, including a bearing beam 1 for bearing or supporting objects that need to be moved. A light bar 3 is slidably connected to the inner wall of the bearing beam 1 to provide guidance and support for the movement of the bearing beam 1 and the moving beam 4. A moving beam 4 is slidably connected to the outer side of the light bar 3. The bearing beam 1 and the moving beam 4 have a certain deformation capacity to provide installation positions for the moving cylinder 51 and the moving clamping cylinder 52. At the same time, the lower part of the moving beam 4 is stretched and deformed by the moving clamping cylinder 52, so that the contact pad 54 and the moving beam 4 clamp the light bar 3.

[0030] Furthermore, a moving component is provided on the outer side of the moving beam 4. The moving component includes a moving cylinder 51. The moving beam 4 or the supporting beam 1 is moved by the extension and retraction of the output shaft of the moving cylinder 51. The moving cylinder 51 is fixedly connected to the lower part of the moving beam 4. The output shaft of the moving cylinder 51 is fixedly installed on the right side of the supporting beam 1 by bolts. A moving clamping cylinder 52 is fixedly connected to the rear side of the moving beam 4. The nut 2 is moved by the extension and retraction of the output shaft, realizing the function of clamping the light bar 3 of the moving beam 4. A movable groove 53 is opened in the middle of the lower part of the moving beam 4 to provide deformation space for the clamping of the moving beam 4 by the output shaft of the moving clamping cylinder 52. The output shaft of the moving clamping cylinder 52 slides through the lower inner wall of the moving beam 4.

[0031] Reference Figure 1 and Figure 3The output shaft of the movable clamping cylinder 52 is threaded with a nut 2, which cooperates with the movable clamping cylinder 52 to achieve clamping. Multiple sets of nuts 2 are provided. The upper front part of the bearing beam 1 has a movable groove 2 56, which cooperates with the bearing clamping cylinder 55, so that its output shaft can drive the bearing beam 1 to deform through the movable groove 2 56. The bearing clamping cylinder 55 is fixedly connected to the front side of the bearing beam 1. The clamping function of the light bar 3 is achieved by the extension and retraction of the output shaft. At the same time, another set of nuts 2 is threadedly connected to its output shaft. The movable cylinder 51, the movable clamping cylinder 52 and the bearing clamping cylinder 55 are all electrically controlled when they need to work. They can clamp automatically without manual operation. The output shaft of the bearing clamping cylinder 55 slides through the upper inner wall of the bearing beam 1. The rear side of the output shaft of the bearing clamping cylinder 55 is fixedly connected to the rear inner wall of the movable groove 2 56. Contact pads 54 are fixedly connected to both sides of the movable beam 4. Multiple sets of contact pads 54 are provided.

[0032] Furthermore, multiple sets of contact pads 54 are fixedly connected to the left and right sides of the bearing beam 1 near the light bar 3. The multiple sets of contact pads 54 slide on the outside of the light bar 3. The outside of the contact pads 54 is made of rubber, and the inside of the contact pads 54 is provided with iron rings. The rubber on the outside reduces wear on the light bar 3 and increases the clamping force. At the same time, the iron rings can increase the structural strength of the contact pads 54. There are two sets of light bar 3, moving beam 4 and moving components. The two sets of moving components are flipped. The two sets of light bars 3 are arranged in parallel, which can improve the stability and reliability of the bearing beam 1 when moving. It is similar to the following caterpillar walking method, with one end fixed and the other end moving, thus realizing the theoretical unlimited travel distance.

[0033] Working principle: When in use, the object to be moved is fixed on the bearing beam 1. When it needs to be moved, the output shafts of the two sets of moving clamping cylinders 52 retract, driving the nut 2 to move. The moving beam 4 is clamped and deformed through the movable groove 53, so that the contact pads 54 on the left and right sides of the two sets of moving beams 4 and the moving beam 4 are in close contact with the two sets of light bars 3, realizing the function of clamping the light bars 3 and ensuring the stability of the two sets of moving beams 4 at this position.

[0034] At the same time, the output shafts of the clamping cylinders 55 on the two sets of bearing beams 1 extend out, and the deformation is relieved by the restoring force of the bearing beams 1 themselves, so that the contact pads 54 on the bearing beams 1 no longer contact the light bar 3, and the clamping of the light bar 3 is released.

[0035] At this time, the output shaft of the moving cylinder 51 extends, causing the bearing beam 1 to slide on the two sets of light bars 3. Then, the output shaft of the moving clamping cylinder 52 extends to release the pressure on the moving beam 4, causing the output shaft of the bearing clamping cylinder 55 on the bearing beam 1 to retract, causing the bearing beam 1 to be squeezed and deformed through the movable groove 56, thus clamping the two sets of light bars 3.

[0036] By retracting the output shaft of the moving cylinder 51, the two sets of moving beams 4 are driven to slide on the light bar 3. Then, by repeating the above operation, the bearing beam 1 can slide in one direction on the two sets of light bars 3. When it is necessary to move in the other direction, the above operation can be reversed.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
